CONVERSION OF AIR CLEANER TO USE A PAPER ELEMENT
Joe Foerster of N. Hollywood CA has converted the oil bath air cleaner on his Series 62 sedan to use a
modern paper element. He did the job in such a way that it is not visible. Joe put together a series of
photos and descriptive text regarding the air cleaner's conversion which can be found at the following web
site: http://bobnjoe.com/car/1949/blog2/archives/2007/11/entry_125.html Below is a picture of Joe’s car,
appropriately named “49er”, with its converted air cleaner ensconced under the hood.

HOW TO HOOK UP YOUR ‘49’s UNDER-HOOD HEATER HOSES
(The following resulted from an exchange of emails between Herman Desser and Jay Friedman. After
having done a frame-off restoration of a prize-winning ’48 convertible, Herman saw the light and is now
doing the same to a superior ’49 convertible.)
Before hooking up the hoses, observe that the defroster core and motor on the driver’s side firewall has
three pipes pointing downwards. Two of these pipes are on the inboard side of the defroster, one of which
is in front of the other. The third pipe is at the outboard side of the defroster.
Directly under the defroster, sitting on the frame rail, is a T shaped pipe fitting (to which hoses will be
connected). The T connection sits on the frame in an upside down position, something like this ┴, with the
axis of its bottom facing longitudinally toward the front and back of the car.
From the pipe connection at the back of the driver's side cylinder head, a short hose goes through an Lshaped
elbow pipe (which looks like this: ┘) to the front pipe of the two inboard pipes on the defroster.
From the back pipe of the two inboard pipes on the defroster, another hose runs under the car’s body to the
driver's side under-seat heater. A third hose runs from the outboard pipe on the defroster straight down to
the upward facing pipe on the ┴ (or T) connection. (See the photo on the next page.)
From the second pipe on the driver's side under-seat heater, a hose runs across the top of the frame to the
passenger's side under-seat heater. From the second pipe on the passenger's side under-seat heater, a hose
runs back over the frame to the driver’s side of the car’s underside, and then all the way to the backward
facing pipe on the ┴ (or T) connection. Another hose runs from the front facing pipe on the ┴ (or T)
connection, up through a clip on the inner fender, to the pipe on the left side of the water pump.
If you need further help making sense of all this, contact Jay or Herman.
